Have an idea for a dataset that should be integrated into IYP? Feel free to propose it by opening a new discussion. You should describe the dataset, why it is potentially useful, and, if possible, provide some initial idea for modeling the data.
The discussion is used to decide if we want to integrate the dataset and how to model it. So feel free to propose a dataset even if you have no concrete model in mind.
If it was decided that the dataset should be integrated into IYP, we will convert the discussion into a GitHub issue. At this stage it is open to anyone who wants to implement a crawler for the dataset.
For a detailed description on how to write your first crawler and contribute to IYP take a look at the IHR contributing guidelines and the crawler instructions.
